Hello, my name is Sera, I have some questions about a potential pregnancy, I had my period from 8/14 to 8/20 and I spotted on 9/4 and 9/27, no sign of period, and I ve taken four pregnancy tests and it says it s negative, I ve checked my cervix, three days ago it was soft, then very hard, now soft again.. I want to know if I m pregnant be ause I ve been trying to conceive since November with my husband, is there something wrong with my reproductive system?
